Carbon neutrality

Hitachi Energy is at the forefront of the energy transition by collaborating with customers and partners to support worldwide efforts to reduce the impact of greenhouse gases  such as sulfur hexafluoride (SF₆).

SF₆ has been the norm in the industry for decades, but that will soon change. Even though SF₆ has excellent insulation capabilities, it has a high Global Warming Potential (GWP), and its life-cycle management requires careful handling. ​​

As the first big step forward, we launched our EconiQ® high-voltage portfolio in 2021 to phase out SF₆ and enable the industry to transition to eco-efficient solutions. Since then, EconiQ has achieved multiple world-firsts in SF₆-free high-voltage technologies and is becoming widely adopted across continents.

A new era of EconiQ is coming. In CIGRE Session 2024, we have unveiled two truly iconic EconiQ additions that demonstrate how the scalability of our technology plays a fundamental role in the effective elimination of SF₆.

Join us on our journey to an SF₆-free energy future!

World’s first 550 kV eco-efficient circuit breaker

Hitachi Energy’s latest sustainable innovation that  scales eco-efficient technology to the highest voltage ratings and marks a significant milestone in the journey to phase out SF₆ from the grid.

EconiQ 420 kV circuit breaker

This breakthrough technology is a significant milestone in the industry  to transmit large amounts of electricity over long distances while eliminating significant volumes of SF₆.

EconiQ Live Tank Circuit Breaker 420 kV

The latest addition to Hitachi Energy’s EconiQ high-voltage line that is as reliable ast he conventional solution and operates with an eco-efficient gas mixture that significantly reduces the environmental impact.
